_____ is the closest celestial body to our earth.a)Earthb)Galaxyc)Moon...
Moon is the nearest celestial body to our earth. Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.

_____ is the closest celestial body to our earth.a)Earthb)Galaxyc)Moon...
The Moon is the closest celestial body to Earth


The Moon is the Earth's only natural satellite and is the fifth-largest moon in the solar system. It is located at a distance of approximately 384,400 kilometers from Earth and takes about 27.3 days to orbit our planet.


Why is the Moon important to Earth?


The Moon has played a significant role in shaping the Earth's environment and its evolution. Some of the ways the Moon impacts the Earth include:



  • Stabilizing the Earth's tilt, which helps to maintain a stable climate

  • Causing tides in the Earth's oceans due to its gravitational pull

  • Providing a light source at night, which has influenced human behavior and culture



Exploring the Moon


Since the first humans landed on the Moon in 1969 during the Apollo 11 mission, several other countries have sent spacecraft to explore the lunar surface. Some of the key discoveries from lunar exploration include:



  • The Moon has no atmosphere or magnetic field

  • The lunar surface is covered in craters, mountains, and vast plains

  • The Moon has water ice in some of its craters in the polar regions



Overall, the Moon remains an important object for scientific study and exploration, as well as a cultural symbol for humanity's curiosity and exploration of the cosmos.

Similar UPSC Doubts

Read the information given below carefully and answer the following question.Theorists are divided concerning the origin of the Moon. Some hypothesize that the Moon was formed in the same way as were the planets in the inner solar system (Mercury, Venus, Mars, and Earth)—from planet-forming materials in the presolar nebula. But, unlike the cores of the inner planets, the Moon’s core contains little or no iron, while the typical planet-forming materials were quite rich in iron. Other theorists propose that the Moon was ripped out of the Earth’s rocky mantle by the Earth’s collision with another large celestial body after much of the Earth’s iron fell to its core. One problem with the collision hypothesis is the question of how a satelliteformed in this way could have settled into the nearly circular orbit that the Moon has today. Fortunately, the collision hypothesis is testable. If it is true, the mantle rocks of the Moon and the Earth should be the same geochemically.Q.According to the passage, Mars and the Earth are similar in which of the following ways?1. Their satellites were formed by collisions with other celestial bodies.2. Their cores contain iron.3. They were formed from the presolar nebula.

Read the following 1 Passage and answer the items that follow. Your answers to these items should be based on the passages only.Recently some scientists have concluded that meteorites found on Earth and long believed to have a Martian origin might actually have been blasted free of Mars’s gravity by the impact on Mars of other meteorites. This conclusion has led to another question whether meteorite impacts on Earth have similarly driven rocks from this planet to Mars. According to astronomer S. A. Phinney, kicking a rock hard enough to free it from Earth’s gravity would require a meteorite capable of making a crater more than 60 miles across. Moreover, even if Earth rocks were freed by meteorite impact, Mars’s orbit is much larger than Earth, So Phinney estimates that the probability of these rocks hitting Mars is about one-tenth asgreat as that of Mars’s rocks hitting Earth. To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions. He found that 17 of the 1,000 particles would hit Mars.Q.According to the passage, which of the following events may have initiated the process that led to the presence on Earth of meteorites from Mars?
